Ben ,
What about "nmap -sV" ? this will still give you a complete list of
open ports , but also will retrieve the banners. I think it should be safe
to say that any *real* program will respond with a banner , so ,only the
ports with banners will be the ones you should pen-test.

Subject: RE: All tcp ports open?
I am not sure what is doing this, but I assume it is a
software (or some
kind of) firewall/hids, can anybody point me in the right direction?
I am pen-testing a Windows webserver, and a port scan reveals ALL tcp
ports open. hping also confirms that a SA is returned for any
S packets
sent to any port I try. I can connect via netcat any of the
ports, and
send data, but nothing is returned. In order to verify services, I am
required to connect and check for a banner or send
appropriate protocol
commands to elicit a response.
Has anyone seen this, or have any idea of what this is?
